v John Osterinann, Glendale, N. Y. Application March 5, 1935, Serial No. 9,472 .2 Qlaims. (or. 293-218) stile showing my thereto;

lhis invention relates to window stops, an object of the invention being to provide on the stile: of an upper sliding window sash an improved device which will engage the meeting railf'b'f a lower vwindow sash and permit limited upward movement of the lower sash or downward movement of the upper sash so as to ensure a proper ventilation of the room and yet prevent an opening of the window sufficient to admit a burglar.

A further object is to provide a device of this character in which a stop arm is normally positioned within an open housing to permit the sashes free sliding movement and provide improved means for holding the arm in the housing against accidental displacement yet permit the arm to be manually moved to either of two positions to stop the opening movement of the sashes at two different adjustments.

With these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts, all of which will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawing- Figure 1 is a view in longitudinal section through a window frame and through sliding sashes, indicating one position of adjustment of my improved sash stop;

Figure 2 is a similar view illustrating another position of the sash stop; I

Figure 3 is an enlarged face view of a window improved device secured Figure 4 is a view. in longitudinal section on the line 4/4 of Figure 3;

Figure 5 is a fragmentary view in section on the line 5/ 5 of Figure 4; and

Figure 6 is a perspective viewof the block adapted to be secured to the meeting rail of the lower sash.

I represents a window frame in which upper and lower sliding sashes 2 and 3 are mounted. To a stile 4 of the upper sash my improved sash stop is secured, and the stile 4 is sufiiciently recessed or countersunk, as shown at 5, to accommodate the same. The device includes an elongated open front housing 6 located in the recessed or countersunk portion of the stile and having a facing plate I which is secured to the face of the stile by screws or other suitable securing devices 8.

The rear or inner wall of the housing 6 is, throughout the lower portion thereof, substantially parallel to the face plate I, but said wall at its upper portion'is tapered or -in'clined,'fas shownat9. It represents a'stop jarmwhich at oneendls :pivotally secured in the. intermediate portion-of the housing by means of a rivet I l and thispiv- I0 the housing has an opening [3, and back of this opening l3, a spring I4 is located, the ends of the spring being projected into recessed en-. 10

largements I5 on the housing, and the intermediate portion of the spring engaging the pivoted end of the arm. The flat portion ll of the pivoted end of the arm is so located that when the lower end of the arm is free to swing out- 15 is secured to the meeting rail l5 and adapted to 20 Q contact with the end of the arm l0, limiting the opening movement of the sashes.

The arm l0 adjacent its lower end is provided with a curved hook l8 which, when the arm is within the housing, engages a ball catch IS. The 25 ball catch 19 includes a rearwardly projecting flange 2!] integral with the housing and having an opening 2| therein of slightly less diameter than the major diameter of the ball, and back of the ball a spring 22 is located, confined at its 30 edges in grooves 23 in lugs 24 on the housing, and the intermediate portion of the spring bears against the ball resiliently projecting the same beyond the flange 20 and in the path of the hook it. Thus, when the arm is forced to its position within the housing the hook I8 will engage the ball catch and the latter will ride over the hook and resiliently hold the arm in the housing. To facilitate the outward movement of the free end of the arm the lower end of the housing is formed with a finger-receiving recess or pocket 25 so that the operator may insert the thumb or finger in said recess or pocket under the free end of the arm I!) to swing the same outwardly.

Figure l in full lines and Figure 4 in dot and 4 latter position will lieagainst the inclined wall Q of the rear of the housing and-project the hook portion 8 of the arm sufliciently to engage the 'block I! on the lower sash. It will thus be noted that the arm may lie within the housing, permitting the free movement of the sashes, or it may beswung to either of two positions to allow the sashes limited open movement. 7

While I have illustrated what I believe to be the preferred embodiment of my invention, it isto be distinctly understood that various slight changes may be made with regard to the form and ar rangement of parts withoutdeparting from my invention, and hence I: do not limit myself vto the precisedetails set forth but consider myself at liberty to make such changes and alterations as 'fairly' fall within the spirit and scope of the claims.

What I claim is:

1. A sash stop, comprising an open front hous ing adapted to be secured to the stile of'an upper' sliding window sash, an arm pivotally secured at one endin the housing, a hook on the arm near itsfree end, said arm adapted to project from the ;housing to position its lower end for engagement with the meeting rail of a lowerrsliding window sash, and adapted when swung upwardly to position its hook for engagement with the lower sash,

- a spring engaging the pivoted end of the arm and adapted to hold the same in either of said positions, and a spring-pressed balljcatch' in the lower portion of the housing adapted to engage the hook and hold the arm within the housing.

2. A sash stop, comprising an open front housing adapted to be secured to the stile of an upper sliding window sash, an arm pivotally secured at one end in the housing, a hook on thearm near its free end, said arm adapted to project from the housing to position its lower end forjengagement .-,With the meeting rail of a lower sliding window sash, and adapted when swung upwardly to position its hook for engagement with the lower sash,

,a spring engaging the pivoted'end of the arm and adapted to hold the same in either of said positions, a transversely extending perforated flange at the lower portion of the housing, a ball projected through the perforation, and a spring secured at its ends to the housingand intermediate its ends engaging the ball pressing the same into contact with the hook to holdthe arm within the housing. 7 o
